The plot is basically a woman who begins to make skincare using recipes from her French grandmother's diary. It was peak "chick lit" era, so very light reading. Perhaps around 2005? The only things I remember is there was the vital ingredient of petuis (sp?!) and there was the usual romantic interest will they/won't they thing and the fact that she had a pile of cashmere from N Peal and was given this dressed down but in a very chic style vibe. Random I know so if anyone can help I would be amazed!!
